uiviewcontroller - iPhone - presentModalViewController with transition from right

Question

I'm using presentModalView controller and pushing the transition to new view via its controller. And I'm using following code to do the transition (which is working fine)

    [self presentModalViewController:myViewController animated:NO];
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[myViewController.view layer] addAnimation:animation forKey:@"SwitchToView"];  

but the problem is that, its showing blank white screen and then transition starts. How to avoid this?

Answer 1

first add animation then present

CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[myViewController.view layer] addAnimation:animation forKey:@"SwitchToView"];  


[self presentModalViewController:myViewController animated:NO];
